Vitta virginea, the virgin nerite, is a species of sea snail, a marine gastropod mollusk in the family Neritidae.

Distribution

This species is widespread from the Bahamas, Bermuda, Cuba, West Indies, Greater and Lesser Antilles, Dominica, Puerto Rico, Central America (Panama, Guatemala, Costa Rica), Brazil, Venezuela, Suriname, Colombia, Mexico, Texas and Florida.

Habitat

Vitta virginea can withstand large changes in salinity and therefore may live in freshwaters, in marine and in brackish waters. These sea snails occur in rivers and streams, in estuaries and in the sea, on sand, silt and stones, brackish ponds and mangroves.
